| Abstract/Contents: | SUMMARY: "Freshly harvested seeds of Poa annua L. collected in south Louisiana were stored in moist soil at seven temperatures between 5 C and 35 C. At monthly intervals, seed lots were removed and germinated at each of the seven temperatures. Seeds were dormant for at least 1 month at all test temperatures. Seeds stored for 2 months at 30 and 35 C showed conditional dormancy; there was 100% germination at 10 or 15 C, and poorer germination at 5 or 20 C. Seeds started to lose viability after 2 months at 35 C and were dead after 7 months. In seeds stored at 10-30 C, there were increased percentages and a wider range of germination temperatures as storage time or storage temperatures increased. Seeds stored at 10 C remained dormant for 9 months, but by 10 months of storage the seeds germinated only at 5 or 10 C. Nearly all seeds stored at the same temperatures in air dry soil remained dormant for 6 months, regardless of storage temperature. These results differ from other reports of low temperatures breaking seed dormancy in Poa annua L. and suggest an adaptation to subtropical climates." |
